It's quite possible what you have come across is called "custard" over here. Ambrosia custard is gorgeous. You pour it over everything that's dessert. You can do it hot over something cold, or cold over something hot. I'm guessing they've called it a 'cream' because if you saw 'custard' you'd think it would be rather thick, like an egg custard. 'Devon' is where it comes from, and cows in Devon are notorious for their cream. It's probably yellowish and as thick as pudding that's not quite set all the way. It'll taste vanilla-ish.
Go ahead, buy the can, heat up an apple pie and pour the cream over a slice. Oh, or maybe over a strawberry rhubbarb crumble. Oh yummy!
